The detailed description which follows is given With reference to one otthe panties, and it Will be understood that all of the parts describedare duplicated :tor the other purity, With the exception of the gloryhole furnace Which operates alternately with both of the punties.

The stick-up device.

The stick-up device by which the glassware is attached to the punty isshown. in Figs. 1, 4, 6, and 8, and consists ot a coinpressed aircylinder 30 supported on a stand ard 31 carried by a transverse member32 l I of the frame 11. The cylinder' 30 contains a piston 33, thepiston` rod 3l ot which carries at its-upper end a block`35 Which isloosely surrounded by a sleeve 36 to which is removably attached a capor die 37 which corresponds in size to the tumblerl T, and may bechanged to tlt'diderent sizes and shapes of glassware. Springsp38 areinterposed between the block 35and `the head of the sleeve 36, andprovide a resilient support for the tumbler and permit the cap 37 toyield when the piston is raised to bring the tumbler into contact withthe underside ot the punty 3. Suitable air pipes 39 supply air to thestick-up cylinder 30 and are attached by means of dexible hoseconnections 40t0 pipes 41, to which compressed-air trom the tank 13 issupplied through pipes 42 and 13 and a valve 44. The valve 44 isautomatically controlled by a cam 45 carl'ied by the cam shaft 26, andfor this purpose is provided with a spring-pressed valve rod 46 carryinga roller 47 which runs on the cam 45. The cam 45 is so shaped as tocause the valve ll to admit air to the lower end of the sticloupcylinder 30 at the proper time to raise the tumbler 'I which has be"placed upon the cap 37 by a workman.

interfase Y The pin/tty (um. As best shown in Figs. e and 7, the nunty 3has an enlarged head 50 to receive the glassware and is attached bymeans et a pin 51 to a chuck 52 carried at the lower end4 ot' asliding,r rod 53 which is slidably teathcred in a sleeve 54, to' theupper end of which is att-ached a bevel pinion meshing With a bevel gear5,6 that is keyed to the shaft 4 which is mounted in bearings 5S securedto the underside of a. transverse plate 59 carried by the trame ll. Aspring surrounds the reduced upper end portion ot' the rod 53 and isconlined by a nut 61 which is screwed into the upper end of the sleeve54. il nut 62 is screived upon the upper end ot the rod and limits thedownward sliding moven'ient ot the rod in the sleeve 54. The sleeve 5lhas a tlange 63 below the bevel gear which supports the sleeve 54 in atube 6l which is screwed into a 'forked yoke 65, the two arms et whichare provided with bearings 6G and o? which loosely surround the shaft tand have suitable bea ing brasses G8. The bearing 6G of the yoke 65carries a pinion 69 which is engaged by the vertical panty-operatingracl" 6. The rack (l is secured to the piston rod 7l of a verticalcompressed ai1eylinder 72 which is operated by means of valve 73controlled oy a cam Tet on the cam shaft 2G through a sl'iring-pressedvalve rod 75 having a roller 76 running on the cam 74. The cylinder 72is so operated by the cani 74 as to swing the panty arm to the severaloperating; positions described above.

The rotation of the punty rod 3 which is required at the lire polishingand linishing positions is produced by a horizontal compressed aircylinder 77 which osoillates the sbatte, thereby oscillating the pantyrod 3 through the bevel gear 56, thefbevel pinion 55 and the sleeve 5ewhich, -s: above, feathered to the rod 53 tm ries the pnnty 3. Ahorizontal 78 is carried by -the piston .rod 79 of the cylinder 7 7 andmeshes with a gear 30 which is keyed direct-ly to the shaft 4l.

lWhen the pantyl is rotated back and forth itis necessary that thedirection otrotation et the panty be changed instantly, because anypanse'between rotationslwould give 'the plastic tumbler time te lose itsshape. ln order to produce this instantaneous chanm ve sing ir..direction We' emp` `which is bestelle-Warn Figs. ,L v l.

259 and 260, respectively. AThe valve 261 controls the admission ofcompressed air from the tank 13 to the central compressed air cylinder'121 which shifts the glory hole furnace lengthwise, while the valve 262controls the admission of compressed air to the 'cylinder 125 which:shifts the gloryhole furnace sidewise. Pipes S263 connect the valve 261and the cylinder 121, while tbe ends of the pipes 264. which-connect thevalve 262 and the cylinder 125 are shown on Figs. and 5, the rest of thelatter pipes being omitted from the drawing for the sake of clearness..lbc air connections to the glory hole furnace are through rubber hosewhich permit the glory hole furnace to The pipe 412 conductsconipressed-air from the tank 13 to the valves 44, as described above,through a manifold pipe from which branch pipes a3, 43, 431 and 430 leadto the valves Lil, 2(517 73 and 262 respectively.

The 'two panty arms operate alternately so that \.'hejn one of thepunt-y arms brings a tumbler to the glory hole the other punty ermbrings a previously Fire-polished tun1- bier to the hurling position.'lhe glory hole furnace shifts from side to sidey while the panties areswinging in order to cooperate with the two panties alternately.

The operation of the several mechanisms which compose our machine hasbeen deW scribed in connection with the construction of each mechanism,and it nov remains to follow given tumbler in its course through themachine. While the tumbler is still plastic7 it is placed by a. workmanon the cap 37 of the stick-up device, as shown in Fig. 8. The cam thenoperates through the valve lei to admit air to the stick-up cylinder 30,and, the tumbler is thereby raised and pressed against the underside oi?the panty which, at the moment., is directly above the stick-up de' icc.rllhe stick-up device then lowered automatically and 'the panty arlmcarrying the tumbler with it.I then swings up to therigbt until itreaches the horizontal position opposite to the glory hole furnace,which has' meanwhile been shifted by the cylinder 125 into the properposition on the trac-ks 1l?. This swinging movement of the panty arm isproduced by 'the rack G actuated bythe cylinder 72., `which in turn. isoperated by the valve T3 controlled by the cam Tel. ln its upwardmovement the panty arm strikes the stein 2236 of one ofthe poppet valves235 and the stem 253V of the dash pot or air cushion 252. rl'fhemovement `of the panty arm is thereby checked without shock, and at the.same time air is schuit-ted .to the cylinder 77 which immediatelybegins' to rotate the panty arm bach and forth through to adm it air tothe forward end of the cylinder 121, which thereupon pulls the gloryhole-furnace forward to enclose the tumbler. and heat the tumbler to therequired temperature, which may be regulated by speeding up or slowingdown the movements of .the punt-y arm by means of the hand air valves..or by opening or closing the burner 130. The cam 255 is preferably soshaped that after the tumbler has been in .thcl glory hole lor a fewmoments the glory hole furnace is pushed back from the tumbler and thecylinder 11T is then automatically operated to drop the shutter 139 infront of the glory hole furnace7 thereby cooling the edge of thetumbler. After a short interval the cylinder 1&7 is again automaticallyoperated to raise the shutter 13S) and the cylinder 121 is then operatedagain to bring the glory hole furnace forward to receive the tumbler asecond time and give it an additional polish. Then the glory holefurnace is again moved back tov free the article and permit lit to bemoved to the finishing position. This double treatment in the glory holefurnace permits the' edges or other thin portions of the glass. articleto cool slightly between the two lirepolishing operations, therebypreventing the thickening of the edge or other thin portion of thearticle. lf desired, the operating cams may be so constructed as to movethe glory hole back and forth three or more times for each tumbler.

lWhen the lrepolishing operationl is completed the cylinder 72 is againoperated by the cam 74 to raise the rack 6 and thereby swing the puntyarm through an angle of 180O which brings the vfire-polished tumbler tothe buflingposition. lVhil'e arriving at. this position the purity armengaves the stems 23 and 253 of the poppet valve 235 and the air cushion252 which is on the side of the machine toward the finishing position,and the poppetvalve n thereupon operates to again rotate the panty armAs soon as the tumbler reaches they finishing posi-` tion, the outsidebuller 8 is lowered upon it by thev automatic withdrawal of the wedge4180 by means of the spring 188 which at this time is left free by thecam 186. The outside bull'er S is reciprocated continuously by the cam170. f

The inside buffer 9 also engages the tuinbler as soon as it reaches thebufiing position, and is reciprocated continuously by nfeansof thecanif`2'11.

lfter the, baiting operation is completed the outside butler is raisedby means of the cam 186 acting througbthe Wedge 180, and the cylinder 72 is again operated bythe cam 74 to lower the rack 6, which swings thepunty arm 3 downtoward the sticking-up position.
